Installed the app on Nexus 6 and compared the recorded light levels with calibrated Konica light meter. Readings were very inaccurate. 25fc on light meter is showing as 38fc on app. Even after calibrating the app, the light levels at extreme (low/high) are always inaccurate. Tested multiple values between 2fc to 350fc.
Seems to work reasonably well on HTC One (m7). Light levels seem to respond step-wise rather than a smooth gradient - that could be due to the phone's sensor. One reading at work brought the site manager round with a "proper" meter - he agreed lighting was inadequate & promised improvements !
The scale is a bit jerky in it's readout but not terribly slow. As far as I can tell, seems accurate. Works as advertised.
Well the app works great I've tried different locations so I can verify it was doing what I expected for it to do... However I do not know how to calculate or do what I need to with the numbers it gives out , somebody transfer 10000 in English for me please
no option to change camera.....uses front by default which defeats the point of the app. Cant see the screen when taking readings as a result.
I used this app to measure the brightness of my winter depression light. This was really useful as it proved i was sitting too far away from my light to be effective.
